"McLaren Hybrid Car Fiasco: A Tale of Misinformation and Malfunction" A disgruntled owner of a McLaren hybrid car has shared a shocking story of poor communication and technical issues with the luxury vehicle's dealership. The owner, who had been abroad for three months, was given questionable advice by the service advisor before leaving, including not plugging in the charger to prevent the hybrid system from draining the car's battery. However, upon returning home, the owner discovered that the 12-volt battery was fully charged, contrary to the advisor's warning. But the good news was short-lived, as the owner soon encountered a series of error messages and a "Hybrid system fault" warning when attempting to charge the high-voltage battery. The incident has raised questions about the reliability and communication of McLaren's dealership and the engineering behind the hybrid system.
I can't believe the timing worked out so "nicely" that I was able to reuse all but one word from the title of my previous post. So after coming home from being abroad for 3 months, I was looking forward to drive my cars, especially since it's one of the first sunny/warmish weekend of the year here in PNW. Before I left, my service advisor told me that I should not plug in the charger because the software for the hybrid system would fully drain the battery and fully brick the car (I know it doesn't make sense, but hey, I don't think logic is a strong suit for software engineers at McLaren), whereas if the 12 volt battery dies after my trip then roadside assist will be able to just jump the car. I was told to leave my car window open during my trip, because McLaren doors can't open if the windows don't come down a bit, and the windows don't move if battery is fully dead. Yeah I know, amazing ownership experience for a 6 months old $300k car right? So to my pleasant surprise I discovered that the 12V batter wasn't dead when I got back home. I was able to unlock the car and notice the 12V battery was at 100% with the hi-voltage battery being at 20%. "Holy shit, the HV battery maintained the 12V battery using its own charge like it's supposed to. Maybe I was being too harsh to McLaren engineers?" But I suspected things weren't as rosy as I hoped when I plugged in the charger trying to charge the HV battery. I was greeted with the most amazing error message: "Battery state too low, unable to charge". Like I said, logic isn't the strong suit for engineers at McLaren. Either that or English. Or both. I don't even fucking care at this point. Then after getting into the car and tried to turn it on, I was greeted with the old friend "Hybrid system fault" and a dashboard of Christmas lights. The last time this happened the towing company had to use these to tow the car out of the garage. But this time I'm more prepared by leaving the window open, so hopefully they can jumpstart the battery this time and disengage the parking brake. But I have a feeling that won't work out. I guess I'll be playing the new Resident Evil game this weekend lmao. I heard it's great because it's not made by software engineers at McLaren. submitted by /u/cookingboy [link] [comments]
